High impedance faults: from field tests to modeling
(Springer, 2013-09-18)
High impedance fault modeling and location for transmission line
(Cartagena de Indias, 2021-04-07)
A fault in a power system generates economic losses, security problems, social problems and can even take
human lives. Therefore, it is necessary to have an efficient fault location strategy to reduce the exposure
time ...
